“Medical tourism” is the keyword phrase. Tons of choices available. I expect the Nazis in the federal criminal syndicate to restrict travel to foreign countries for medical treatment. When that starts, it’s time to burn DC to the ground and kill all the fascist bureaucrats.
I expect the Federal government will restrict foreign travel for several reasons, one of them being that’s what totalitarian states do. They do not want their slaves escaping.
